Dear all,
Just two small comments:
- I think NM-WG already proposed a data model in UML (In its first
GFD document). So, may be NML can propose a UML version for
simplifying the discussion between
the two groups as suggested by John.
- RDF is the best choice for letting different communities develop
their own ontologies and make them interoperable. I think it is a
very good choice made by the NML group.
So we mainly need to aggree within NML-WG for the ontology we need in
the considered context.
